| Abstract(in English) | Many of the conventional methods combine the attributes of entities in an ad hoc manner to acquire View. In some cases, denormalization is performed. In this case, the configuration method of the View is not consistent, and the maintainability and readability of the applications are deteriorated. Meanwhile, aggregate patterns are introduced in domain driven design (DDD). Divide the domain model into consolidation units and set classes to be aggregate roots for each. And it is the idea to make the aggregate root function as a facet, and conceal the classes other than the aggregate root. Although it is an easy-to-follow guideline, criteria for determining aggregate roots are not specified. Therefore, in this paper, we propose a method to set consolidation roots by analyzing existence dependence of task requirements. Specifically, modeling while distinguishing existence dependency, attributive dependency, and deemed attribute dependency targeting fulfillment in the businesses, constructing a class diagram as a domain model, finds aggregate roots, and provides View in Mapper pattern . By doing this, we aim to offer a consistent view of the view that excludes the designer / implementer 's personality to the business applications. |
